## Discrepancy

DURING INSPECTION OF THE LANDING GEAR, THE OUTBOARD LT LANDING GEAR BRACKET WAS FOUND WITH HEAVY INTERGRANULAR CORROSION (I/G) TO THE LOWER FITTING.  SUSPECT CAUSE IS IMPROPER HEAT TREATING DURING MANUFACTURE.  SUBMITTER STATES THIS IS THE FOURTH SUCH FITTING FOUND WITH I/G CORROSION.  RECOMMEND CLOSE INSPECTION OF LANDING GEAR BRACKETS DURING INSPECTION OF OLDER AIRCRAFT.
